Abstract (en)
First and second three-phase inverters having self-diagnosing circuits are connected to three-phase windings of a three-phase double-winding type motor, respectively, and first and second servo controllers having self-diagnosing circuits are connected to the three-phase inverters, respectively. When an abnormality occurs in the three-phase inverter or the servo controller, the occurrence of the abnormality is signaled to the servo controller. When abnormality occurs in the three-phase inverter or the servo controller, the occurrence of the abnormality is signaled to the servo controller, thereby stopping rotation of the motor. <IMAGE>
